The Liberal Party did not field a candidate; it had last contested the seat in 1923, finishing a poor third.
Results
On a slightly-reduced turnout, the result was a victory for The Marquess of Clydesdale, who won 54% of the votes. He was re-elected at the next two general elections, remaining East Renfrewshire's MP until he succeeded to the Dukedom in 1940, triggering another by-election.
